The a1000 inverter is the main model launched by the Japanese Yaskawa inverter brand. This article is mainly about the use of a1000 inverter and its selection skills.
A1000 frequency converterSensorless positioning control:
1. When driving the IPM motor, the sensor (PG) that is usually necessary for position control is not required.
Using the electrical saliency of the rotor of a synchronous motor (IPM motor), the speed, direction, and rotation angle can be detected even without a sensor.
2. Even without a host controller, sensorless positioning control can be achieved.
Through the visual programming function DriveWorksEZ programming, can realize the sensorless position control.
Instantaneous power failure measures suitable for the purpose:
1. Two kinds of instantaneous power failure compensation functions can be selected.
2. It can be used for sensorless control of induction motors or synchronous motors.
Search for the speed in the free-running state and restart easily. Best use: Fans, blowers and other fluid machinery equipped with rotating bodies.
The motor does not enter the free-running state and continues to run. Best use: Instantaneous power outage measures for film production lines, etc.
3. It can be compensated for instantaneous power failure for 2 seconds.
Comply with the standards of semiconductor manufacturing equipment; special equipment such as UPS (uninterruptible power supply) can be omitted; when low voltage is detected, instantaneous power failure compensation is automatically performed.
Energy saving:
1. Using the most advanced energy-saving control technology.
Using the energy-saving control of the frequency converter can realize the high-efficiency operation of the induction motor.
2. Super energy saving when used in synchronous motors.
The high-efficiency synchronous motor and the energy-saving control of the inverter can be used at the same time, which can surpass the induction motor and achieve super energy-saving.
Environmental resistance design:
1. We have enhanced products that are resistant to humidity, dust, oil, and vibration.
2. At the same time, products with protective structures such as dust-proof and drip-proof IP54 are also available.
Reduce noise:
The Swing PWM method is adopted to reduce the harsh noise while suppressing electromagnetic interference.
Suppress high-order harmonics of power supply
1. Standard configuration of high-order harmonic suppression DC reactor (above 22KW)
2. Equipped with 12-phase and 18-phase rectifier options and high-order harmonic suppression filters to suppress high-order harmonics.
Selection Skills of A1000 Inverter
1: The maximum applicable motor capacity is the capacity of the 4-pole, 60Hz, 200V standard motor manufactured by the company. A more rigorous selection method is to make the rated output current of the inverter greater than the rated current of the motor when selecting the model.
2: Indicates the value at the rated output current. The rated input current value is affected by the impedance of the power supply side including the power transformer, input side reactor, and wiring conditions.
*3: The rated output capacity is calculated under the condition that the rated output voltage is 220V.
4: The value when the carrier frequency is 2kHz. When increasing the carrier frequency, the current needs to be reduced.
5: The value when the carrier frequency is 8kHz. When increasing the carrier frequency, the current needs to be reduced.
6: The value when the carrier frequency is 5kHz. When increasing the carrier frequency, the current needs to be reduced.
1: The maximum applicable motor capacity is the capacity of the 4-pole, 60Hz, 400V standard motor manufactured by the company. A more rigorous selection method is to make the rated output current of the inverter greater than the rated current of the motor when selecting the model.
2: Indicates the value at the rated output current. The rated input current value is affected by the impedance of the power supply side including the power transformer, input side reactor, and wiring conditions.
3: The rated output capacity is calculated under the condition that the rated output voltage is 440V.
4: The value when the carrier frequency is 2kHz. When increasing the carrier frequency, the current needs to be reduced.
5: The value when the carrier frequency is 8kHz. When increasing the carrier frequency, the current needs to be reduced.
6: The value when the carrier frequency is 5kHz. When increasing the carrier frequency, the current needs to be reduced.
Closed wall hanging type (NEMA type 1)
1. We need to discuss the capacity of the inverter.
2. According to different installation conditions and motor types, the speed regulation accuracy is different. Please refer to our company for details.
3. The short-time average deceleration torque is the deceleration torque of a single motor decelerating from 60 Hz in the shortest time (depending on the characteristics of the motor).
4. When connecting a braking resistor or braking resistor unit, set L3-04 to 0 (invalid). If it is not set, it may not stop within the specified deceleration time.
5. When the output frequency is lower than 6Hz, the overload protection function can even run within 150% and 60 seconds of the rated output current.
6. Due to capacity and load. For 200 V/400 V 11kW (CIMR AA2A00 56/CIMR AA4A00 31), an instantaneous power failure compensation unit is required to ensure that the instantaneous power failure compensation reaches 2 seconds.
7 Due to the possibility of a short circuit to the ground of the motor coil during operation, protection cannot be performed under the following conditions. The motor cable and the low resistance grounding of the terminal are short-circuited. When the ground is short-circuited, switch to the inverter power supply.

E-cig as a substitute of tobacco mainly reminds people of its potential benefits for health. Four ingredients contain in the e-liquid : propylene glycol, glycerin vegetable, nicotine and food grade essence. Nevertheless, smoke from cigarette contains carbon monoxide, tar, arsenic, ammonia, and many other cyanide and acetone.
